Will do. I use Simon Matter's excellent RPM/SRPM install base.

But what about all the other files (the msgs)?

user/test/1.
user/test/2.
user/test/3.
 etc etc 

My understanding is that it was meant to gather them all up and store
them in a DB.

Whoops! Ok though my problem still is I didn’t know which specific file
it considers as a flat DB, since flat = multiple files (messages).

Well if I cant get this working I am going to install 1.6.22 on the new
machine, then copy over the 1.6.22 files from the old, and then upgrade
1.6.22 on the new to 2.1.8.

Thanks again  for your help!
